In Reply to: RE: Single End Parallel Class A amps. posted by Cougar on February 12, 2014 at 16:18:31
All I was asking was how would that type of single ended amp with the KT120 as the output tube would sound compared to a True SET from those here that may have had the opportunity to either hear or build. I haven't been into (True) tubes amps ( hybrid was the farthest) and haven't had the opportunity to listen to all these different types of SET amps (300b, 211, 845, GM70) to know which will fit MY listening need/s. The only Tube amp I have had an opportunity to hear but it was in a Push Pull configuration was Dynaco ST-70 and maybe a BAT.
So this is the amp I was talking about in the OP. It's a Musical Paradise MP-501 V2 KT120 Single End Parallel Class A tube amp. from what the info on the site says it's not a Push Pull configuration. So that's why I was asking how would the KT-120 in this type of configuration sound compared to a TRUE SET amp from those who had heard it in a SET config.
Btw, I'm currently ordering my parts for a 2 stage with 845 output tube/s in monoblocs. I have about half the parts and will be ordering some MageQuest output transformers. I wanted to use Edcor but their top limit is 1000Vdc and that's right at the point where I'm going run the 845's.
The Musical Paradise MP-501 V2 KT120 amp sounds like a great bargain for a Single End amp and even tho I wanted to build my 845 based amp from scratch I just didn't want to pass up what may be a great deal for a Single End amp without the normal Single End cost that a great SET would cost me if the amp above was right there in sound with a SET. Also if I could get that output power in a Single End amp that would be awesome!
Thank You Tre and everyone else for your info and Opinions.

There is not enough information available to make a good educated guess. If it meets the 55watt per channel specification, then it is not being run in triode mode, and since is says there is no global negative feedback one must assume there is local feedback around the pentode-mode output stage. There are very very few examples of such an approach, so you won't see many reports of direct experience with it. I personally think it has some real promise - but that's just speculation. For what it is, the cost is peanuts at around $20 per pound - if you get it, please post impressions!
Hi Paul,
I will post back if I do get this amp. Seems too good of a deal to past up. :)
I think Tre covered it below. The SEPP will not sound like a true SE(DH)T amplifier, though it might sound single-ended-ish at a gross level. That said, some SET amps DON'T sound like what people think SET amps should sound like, so go figure.
Cheers.
